I have a genuine antique Aboriginal boomerang on the wall. Picked it up in NSW years ago for a small fortune. It weighs a ton, seemingly. It ever hit a critter, and I suppose it has, it'd never know what hit him. I have thrown it to see if it would fly, and it does admirably, but me seeing Mad Max and knowing full well that a weighted object propelled with speed MIGHT hurt my little piddies, let alone my hard enough head, I refrained from trying to snatch it from the air.
